ABSTRACT:
A technique includes applying a charge to a flow plate of a fuel cell stack and depositing a material on at least a portion of the flow plate in response to the charge. In some embodiments of the invention, the technique may be applied to a fuel cell stack that includes a passageway to communicate a coolant. As a result of the technique, the fuel cell stack may include a layer to line the passageway to electrically insulate the stack from the coolant.
